Product details
Overview
CY8C4246PVI-DS402 from Infineon Technologies (formerly Cypress) is a programmable System-on-Chip (SoC) featuring a 48 MHz Arm Cortex-M0 CPU, 64 kB flash, 8 kB SRAM, and four universal digital blocks (UDBs) for reconfigurable logic. It integrates three serial communication blocks (SCBs), four 16-bit TCPWM units, and programmable analog peripherals. Used in embedded control systems requiring field-upgradable logic and mixed-signal integration, such as motor control interfaces and sensor fusion nodes.
For engineers reviewing the CY8C4246PVI-DS402 datasheet, CY8C4246PVI-DS402 pinout, CY8C4246PVI-DS402 application, or CY8C4246PVI-DS402 equivalent, key selection criteria include UDB count, SCB reconfigurability (I²C/SPI/UART), Deep Sleep current (1.3 µA), GPIO drive strength configurability, and SWD debug interface support.
Technical Context
The device implements a single-layer AHB-Lite interconnect linking the Cortex-M0 core to memory, peripherals, and programmable digital blocks. Clocking relies on dual internal oscillators: a trimmable IMO (24–48 MHz, ±2% accuracy) and a 40-kHz ILO for low-power timing during Deep Sleep.
Its programmable digital subsystem uses four UDBs-each with 8 macrocells and an 8-bit data path-enabling custom state machines or logic functions synthesized via Verilog or schematic entry in PSoC Creator. Analog resources include two low-power comparators and configurable op-amp routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M0, 48 MHz max, single-cycle multiply - enables real-time deterministic control loops without external co-processors. |
| Flash Memory | 64 kB with Read Accelerator - delivers ~85% of SRAM access speed for tight interrupt latency in firmware-intensive applications. |
| SRAM | 8 kB - sufficient for stack, heap, and peripheral buffers in compact RTOS or bare-metal sensor node firmware. |
| Digital Logic | 4 UDBs, each with 8 macrocells + 8-bit datapath - supports concurrent custom protocols (e.g., proprietary encoder interface) alongside standard peripherals. |
| Serial Interfaces | 3 SCBs, runtime-reconfigurable as I²C/SPI/UART - allows dynamic protocol switching per channel without hardware change or reset. |
| Power Modes | Deep Sleep current = 1.3 µA @ 3.3 V - enables battery-powered operation for >10 years in wake-on-GPIO sensor monitoring. |
| Debug Interface | 2-wire Serial Wire Debug (SWD) - provides full on-chip debugging using standard Arm tools without JTAG header footprint. |
Pinout & Package
Package: 28-pin SSOP (300 mil), 11.5 mm × 7.6 mm body, 0.635 mm pitch. Compatible with standard surface-mount assembly and manual prototyping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Primary power supply input | Accepts 1.71–5.5 V; powers digital core, UDBs, and most peripherals - enables direct connection to Li-ion or USB 5 V rails. |
| VSS | Ground reference | Common return for all analog/digital domains; requires low-impedance PCB plane for noise-sensitive ADC/comparator operation. |
| XRES | External reset input | Active-low asynchronous reset; debounced internally - eliminates need for external RC network in most designs. |
| SWDIO / SWDCK | Debug interface signals | 2-wire SWD interface pins - shared with GPIOs P0[0]/P0[1]; no dedicated debug header required. |
| P0[0]–P0[7] | Programmable GPIO port 0 | Configurable drive modes (OD, PP, Hi-Z), slew rate, and pull-up/down - supports I²C bus termination, LED driving, or capacitive sensing. |
| P1[0]–P1[7] | Programmable GPIO port 1 | Includes dedicated SCB0/SCB1/SCB2 signal mapping - enables hardware-assisted UART TX/RX or SPI MISO/MOSI without bit-banging. |
| P2[0]–P2[6] | Programmable GPIO port 2 | Supports TCPWM capture/compare outputs and comparator inputs - used for PWM-driven motor gate control or zero-cross detection. |
Key Features
| Feature | Design Value |
|---|---|
| Reconfigurable UDBs | Four independent logic blocks enable synthesis of custom digital functions (e.g., quadrature decoder, CRC engine) without consuming CPU cycles. |
| Runtime SCB Reconfiguration | Each serial block can switch between I²C, SPI, and UART protocols under firmware control - simplifies multi-interface sensor hub design. |
| Deep Sleep with GPIO Wakeup | 1.3 µA retention current with full GPIO interrupt capability - supports ultra-low-power environmental monitors with event-triggered wake. |
| On-chip Flash Protection | Hardware-enforced read/write protection and debug disable - prevents unauthorized firmware extraction or reprogramming in deployed devices. |
| Integrated Analog Peripherals | Two low-power comparators with hysteresis and programmable reference - eliminates need for external comparators in overvoltage or threshold-detection circuits. |
Applications
| Motor Control Interface | Sensor Fusion Node |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C4247LQI-BL483 | Same PSoC 4200DS architecture but in QFN-56 package; includes BLE radio subsystem. | Requires integrated wireless connectivity; higher RF layout complexity and power consumption in active mode. | Select when Bluetooth Low Energy endpoint functionality is mandatory and board space permits larger package. |
| STM32G071CBT6 | Arm Cortex-M0+ core at 64 MHz; no programmable logic; fixed-function peripherals only; 128 kB flash, 36 kB SRAM. | Better raw compute and memory for firmware-heavy tasks; lacks UDB-based hardware acceleration for custom protocols. | Select when application relies on standardized peripherals and deterministic C-code execution dominates over hardware-defined signal processing. |
Compared with CY8C4246PVI-DS402, CY8C4247LQI-BL483 adds integrated BLE but increases package size and RF design overhead, while STM32G071CBT6 offers more memory and higher clock speed but removes field-reconfigurable logic - making it unsuitable for applications requiring hardware-level protocol customization or mixed-signal co-processing.

FAQ
What development tools are required to program CY8C4246PVI-DS402?
PSoC Creator IDE (free, Windows-only) is the official tool for schematic-based hardware configuration and firmware development. It auto-generates peripheral initialization code and supports drag-and-drop component placement. Programming is performed via MiniProg3 or KitProg2 programmers using the SWD interface. ARM GCC toolchain integration is supported for advanced users.
Does CY8C4246PVI-DS402 support true hardware AES encryption?
No. The device does not include a dedicated cryptographic accelerator or hardware AES engine. Security relies on flash protection bits, debug disable, and software-implemented algorithms. For applications requiring certified AES-128/256, external secure elements or higher-tier PSoC families (e.g., PSoC 6) must be considered.
Can the UDBs implement a UART transmitter without using an SCB?
Yes. Each UDB contains macrocells and a datapath capable of implementing fully synchronous logic. Example components in PSoC Creator - such as the "Custom UART Tx" user module - synthesize shift registers, baud-rate timers, and start/stop bit logic entirely within UDB resources, freeing SCBs for other protocols.
What is the maximum operating temperature for continuous use?
The CY8C4246PVI-DS402 is rated for industrial temperature range: –40 °C to +85 °C ambient. Thermal performance is validated up to 85 °C case temperature under specified voltage and load conditions per datasheet Section 11. Derating is required above 70 °C ambient if operating at maximum clock frequency and full GPIO drive strength.
